Abstract

Provided herein are embodiments of a refrigerator valve and method of routing water through a refrigerator with the valve. The valve includes three valve bodies that route water in a refrigerator to different features. The middle valve body is higher than the two outer valve bodies, allowing the solenoid actuators to be mounted in a space-saving manner. The three valve bodies are linked by a central core pin that can be continuous or discontinuous such that the central core pin can provide fluid communication between all three valve bodies or divide the valve into two separate but linked valves. In a valve with a discontinuous central core pin, one valve body is isolated from the other two valve bodies so as to provide a redundant shutoff and allow a filter of a filtration unit to be replaced without having to shut off the water being supplied to the refrigerator.

First claim

What is claimed is:

1. A triple valve, comprising:
a first valve body having a first end and a second end;
a second valve body having a first end and a second end;
a third valve body having a first end and a second end; and
a central core pin that mechanically connects the first valve body, the second valve body, and the third valve body;
wherein the second valve body is disposed between the first valve body and the third valve body;
wherein the second valve body extends beyond a plane defined by the first end of the first valve body or by the first end of the third valve body;
wherein the central core pin defines a continuous interior channel that is in fluid communication with the first valve body, the second valve body, and the third valve body; and
wherein each of the first valve body, the second valve body, and the third valve body comprise:
a port at the second end;
a central bore in fluid communication with the port; and
a passage disposed exterior to the central bore, the passage being in fluid communication with the continuous interior channel and with the central bore.

2. The triple valve of claim 1 , wherein each of the first ends of the first valve body, the second valve body, and the third valve body has a solenoid mounted thereon and wherein actuation of each respective solenoid permits or prevents fluid communication between the respective central bore and the respective passage of the first valve body, the second valve body, and the third valve body.

3. The triple valve of claim 2 , wherein a first end of continuous interior channel is configured to receive fluid from a fluid supply and fluid entering the first end of the continuous interior channel is distributed through one or more of the first valve body, the second valve body, or the third valve body via actuation of the respective solenoid of the first valve body, the second valve body, or the third valve body.

4. The triple valve of claim 1 , wherein the first valve body, the second valve body, and the third valve body are arranged substantially along a straight line, wherein at least two of the first valve body, the second valve body, or the third valve body has a solenoid mounted thereon, and wherein each solenoid has one or more connection prongs that are oriented substantially parallel to the straight line.

5. The triple valve of claim 4 , wherein each of the first valve body, the second valve body, and the third valve body has a solenoid mounted thereon and wherein two of the solenoids are oriented in a first direction and the third solenoid is oriented in a second direction that is 180° from the first direction.

6. The triple valve of claim 1 , wherein the central bore of each of the first valve body, the second valve body, and the third valve body has a first longitudinal axis and the passage of each of the first valve body, the second valve body, and the third valve body has a second longitudinal axis and wherein the first longitudinal axis is parallel to the second longitudinal axis.

7. A method of routing water within a refrigerator with the triple valve according to claim 1 , wherein the first valve body further comprises a first solenoid, the second valve body comprises a second solenoid, and the third valve body comprises a third solenoid, wherein the method comprises the steps of:
supplying water to a first end of the central core pin;
actuating at least one of the first solenoid, the second solenoid, or the third solenoid; and
distributing water to a feature of the refrigerator through the respective first valve body, second valve body, or third valve body of the actuated first solenoid, second solenoid, or third solenoid.

8. The method of claim 7 , wherein the step of distributing water to a feature further comprises distributing water to at least one of an icemaker, a water dispenser, or a pitcher filler.

9. The method of claim 7 , wherein the step of distributing water to a feature further comprises distributing water to an icemaker through one of the first valve body, the second valve body, or the third valve body upon actuating the respective first solenoid, second solenoid, or third solenoid and distributing water to a water dispenser through another of the first valve body, the second valve body, or the third valve body upon actuating the respective first solenoid, second solenoid, or third solenoid.
